HONE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed October 26, 1903- Serial No- 178,558.

To aZZ whom, it may concern:

Be it known that I, MILTON COLE, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Hones, of which the following is a specification.

The object of my invention is to provide an effective substitute for anordinary hone or Whetstone, an object which I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which Figure 1 is a perspective view of my improved hone; Fig. 2, alongitudinal section of the same, and Fig. 3 is a similar viewillustrating a modification of the invention.

The ordinary hone, composed of natural stone, is objectionable becauseit is breakable and is not always of uniform texture throughout, thebest of the natural hones being quite expensive.

I have discovered that aluminium possesses qualities which render itavailable as a cheap and effective substitute for the usual naturalhone, the metal being of close grain and uniform texture and being alsobetter than the natural stone in the respects that it imparts a sharperand more lasting cutting edge than such natural stone and is practicallyunbreakable.

In preparing the metal for use as a hone I prefer to cast it in the formof a block, such as shown in the drawings, which can be used withoutspecial mounting, although in carrying out my invention I may use alighter strip of aluminium mounted in a suitable holder, so as topresent an unobstructed face for action upon the razor or other bladetobe sharpened.

In the use of the hone water is used as a lubricant. (See Fig. 3.)

Having thus described my invention, I claim and desire to secure byLetters Patent- An implement having an aluminium surface for sharpeningedge tools.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MILTON COLE. Witnesses:
